Abstract
Abstract A substantially rectilinear tank for the storage of cryogenic fluids or the like wherein corrugated baffle plates are oriented with respect to each other and to the sideplates of the tank to provide maximum support both for the pressures built up when the container is in use and the pressures exerted on the structure during fabricating processes.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
194 words
A cryogenic tank fabricated of two modules, each of said modules being comprised of a pair of flat rectangular parallel side panels with a plurality of baffle plates extending therebetween and with end wall portions extending between and along three edges of said side panels whereby the module presents one open end, the end wall portions adjacent the ends of said baffle plates being shaped to form communication passages between the spaces formed by said baffle plates, said baffle plates each having side edges adjacent said side panels and being formed with a plurality of parallel corrugations arranged perpendicular to said side panels, said end wall portions and said side edges of said baffle plates being joined to said side panels in a brazing operation performed while compressive forces are applied to said side panels, said corrugation of said baffle plates serving to rigidify said baffle plates so that the latter will withstand the compressive forces applied during the brazing operation, said modules being secured together at their open ends to provide a closed tank, and means forming an inlet in one of said end wall portions adjacent one end of said baffle plates.
